Semen characterization, seasonality of production, and in vitro sperm quality after chilled storage and cryopreservation in the king penguin (Aptenodytes patagonicus)

Research was conducted to examine seasonal seminal traits and to establish short-term and long-term sperm preservation methods in the king penguin (Aptenodytes patagonicus) for use in genome banking and artificial insemination (AI). Spermic ejaculates (n = 87) obtained using a cooperative method were collected across multiple (n = 6, Male 1) and a single (Male 2) breeding season(s). Non-contaminated […]
